The Ritharngu, also known as the Diakui, are an indigenous Australian people of Arnhem Land in the Northern Territory.


Ritharngu is a Yolŋu Matha language. In modern times Ritharngu has been observed to be undergoing significant structural changes away from Yolgnu, with innovations in its morphosyntaxis through assimilation of features characteristic of Nunggubuyu and Ngandi.[1]


The Ritharngu are estimated to have landed estates extending over approximately 2,200 square miles (5,700 km2) east and south of the Arafura Swamp. They also inhabit the area east of the Goyder River, whose tributaries' headwaters form their southernmost frontier. They also inhabit the area around the Mitchell Ranges and the Koolatong River headwaters.[2]
